I'm having the wood refinished from my 87wagon. I took it to a furniture refinishing shop locally and they said about a hundred bucks----but about five weeks to get it done. You are right the haze goes through the entire finish so it all has to be stripped off.
They are using some sort of industrial urethane, but it is the process of sripping the old hard finish off that takes for ever. I've seen their finished product and it looks good as new. Only problem is driving around with the interior looking rough.
The next project around here is to get a computer to post pictures, so if I get that done in the same timeframe as the woodwork, I'll post the results
